If J M = 9 and K M = 4 , what is the approximate perimeter of Δ J K L ? 26.2 26.2 29.8 29.8 31.0 31.0 31.7

Sagot :

Answer:

Correct option is (a)

Step-by-step explanation:

According to question in the triangle ΔJKL

JK = 9 and KL =4

according to the condition of triangle sum of two sides must be greater than the third side

Here sum of its two sides is 9 + 4 = 13

⇒ third side must be greater than 13 say 13.2 = JL

therefore, perimeter of triangle ΔJKL is

JK + KL + JL = 9 + 4 + 13.2 = 26.2

Therefore correct option is (a)
